What is the communication layer in a smart grid?

The communication layer is important in distinguishing Smart Grids from traditional power grids, and in enabling SG applications. It is divided into three categories classified by geographic area (Wide Area Network, Neighborhood Area Network/Field Area Network, and the Premise Area Network).

How do smart grids work?

Smart grids utilize bidirectional communication to function where traditional power grids mainly only use one-way communication. The communication requirements and suitable technique differ depending on the specific environment and scenario.

What distinguishes smart grids from traditional electrical grids?

What separates Smart Grids from traditional electrical grids are the interaction and communication between the different domains. The SG infrastructure can be structured by dividing it in four layers: the application layer, the communication layer, the power control layer, and the power system layer.

What is the difference between a traditional grid and a SG?

Communication play an important role in SGs, as one of the most significant differences between traditional grids and SGs is two-way communication. Traditional power grids only provide one-way communication between the utilities and the customer, whereas SGs provide two-way communication [3, 10].

What are the enabling technologies of smart grids?

Communication is one of enabling technologies of SG. As the number of sensors increase, the amount of data coming to and from the utility increases. 3.1. QoS Requirements for Smart Grids SG applications result in increased data, these applications have different QoS requirements.

Are wired and wireless communication necessary in smart grid environment?

Both types of communication are necessary in smart grid environment. The technology that fits one environment may not be suitable in a different environment. Following is a summary of some of the wired and wireless communication technologies used for smart grids, together with advantages and limitations. 3.3.1. Wired Communication
